I worked in oil and gas in a previous life. The absolute wildest people I've ever met are saturation divers - divers who live in pressurized chambers on ships for months at a time to avoid having to decompress after dives. Fantastic money but you need a few screws loose to handle the work.

A tiny population of workers who really make the most use of their 30k+ watches. But jokes aside, probably one of the deadliest jobs no one hears about. Having to live in cramped quarters with no way out for weeks on end. Reduced life expectancy. Incidents happen. People die, or end up severely incapacitated.

What a giant waste of taxpayer money, built when many - especially in east European countries - were already warning something exactly like this year would happen. Cool technology though.

Why were they warning that this would happen? Who were they thinking would do this?

> ...something exactly like this year...

I don't know what GP meant specifically, but.

Rational energy policy would have assumed that Russia would turn off its gas at some point. Eastern European countries, though, particularly the Baltics, tried to warn other countries that Russia would leverage any energy dependence to assert dominance. As it has.

I believe that's the "this" meant here.

After working in O&G previously, some of the technology surrounding it still amazes me. Take the submersible hot-welding habitat probably used here, or one like it. We have found a way to (somewhat safely) put humans on the bottom of the ocean, in a box, around a metal pipe full of explosive gasses at pressure, for the purpose of shooting molten metal at, or cutting into that metal pipe.

What are we doing?

How much money is “fantastic money”?

Anecdotally, my uncle did this back in the late 80s to 2000s. Towards the end he would make AUD$400-800k a year (depending on how many jobs he took on) which was great money for someone who got into it in his early 20s after dropping out of high school. The catch was the pressure of the environment, needing to be physically in peak shape (my uncle was an anomaly in lasting in the job until his late 40s), and the dang…

> worst I heard was due to the operators giving the wrong gas mix to the chamber

Worst I have heard was the Byford Dolphin rapid decompression incident:

Four diver died instantly in a very gruesome way.

I found this section from another page on the same site amusing: > Nord Stream developed a high environmently-conscious logistic concept which guarantees that transport vessels have not to travel more than 100 nautical miles (185 kilometers). [...] This concept of short trips and environmentally friendly transport saves roughly 200,000 tonnes of carbon dioxide when compared against other options and the use of existi…

Those 150k tons are for heating people's homes. Whereas the spend on the boat fuel is simply for construction of the pipeline so if you can optimize that, that's under your control, as the company laying pipe right now. Though maybe you prefer everyone die of cold until we have a solution to transition out of natural gas without returning to coal or wait 10 years to build more nuclear.

NS2 was started ten years ago and cost around nine billion euros. Nine billion buys a lot of insulation, heat pumps, and wind turbines over ten years. Wheras NS2 was only ever needed so that Russia can turn off gas for Ukraine without turning it off for Germany.

Byford Dolphin is one of the most infamous/gruesome sat diver incidents:

Joe Biden threatened to do it live on air: https://m.youtube.com/watch?v=UKn8TM47BTc

So if they actually blew up the pipeline what would happen if Russia tries to return the favor and do the same to Norway-Polish pipeline that was just opened.

Yeah, that seems like a real trustworthy channel...

Btw. they were talking about heavy sanctions back in the time.

Uncanny how the war escalated around the time NS2 was ready...

For all the talk about how corrupt Eastern European countries are. Russia sure proved western politicians are easy to buy.

This isn't politicians being bribed. It's countries.
